Vinovich joined the NFL in 2001 as a side judge. He was made a referee in 2004 and worked a wild card game as a referee after the 2006 season. In the offseason that year, Vinovich was working out on a treadmill and felt severe back pain. Thinking he injured himself while working out, he went to the doctor where he was told his life was in danger due to an aortic aneurysm. Doctors were able to treat his heart condition, but advised him that officiating games was too dangerous, so he was forced to end his officiating career. (Vinovich also officiated NCAA Division I basketball games and worked in the NCAA tournament.)

After leaving the field, Vinovich served as an NFL observer, where he attended games and scouted and graded NFL officiating crews each Sunday since 2007.

Apparently, the doctors now have given Vinovich a clean bill of health, and he has been cleared to resume officiating.

John Parry was promoted to referee after Vinovich’s departure. Parry was the highest rated referee last season, as he headed the crew that officiated the Super Bowl.

An NFL spokesman declined to comment, citing the longstanding policy to not disclose officiating assignments prior to the day of kickoff.

Haven’t been able to confirm that. Vinovich is in for Scott Green who had an injury last season, so maybe he doesn’t feel 100%. Purely speculative. We do know that Vinovich was listed as a “swing” official (i.e., substitute) when the lockout ended.

Yes, Bill Vinovich II grew up in Midland, PA. His son, Bill Vinovich III is the NFL referee (#52). They are my Uncle & cousin. Interestingly, my Grandfather, Bill Vinovich Sr. was a long-time official in Beaver County sports…his legacy was carried on by my Uncle, who also is an official in the college ranks and now my cousin (NFL). There is a 4th generation Bill Vinovich IIII, my cousin’s son, but he is currently not involved in officiating. Look for him to one day be a sports agent, as he is attending Marquette University for Law.
